I have a problem creating a reverse DNS record.

First of all, I have created a new zone. IP was aaa.bbb.ccc.ddd and Domain was ccc.bbb.aaa.in-addr.arpa.

Second, I have edited the just created zone and I added a PTR record:ddd IN PTR domain.com, TTL 14400

After I saved it and go again to edit the zone, I can see that system added .ccc.bbb.aaa.in-addr.arpa. to the record.

Anyway, after 24 hours, I connected to the console using SSH and run this command: dig -x aaa.bbb.ccc.ddd I saw this output:

; <<>> DiG 9.11.4-P2-RedHat-9.11.4-16.P2.el7_8.6 <<>> -x aaa.bbb.ccc.ddd
;; global options: +cmd

ddd.ccc.bbb.aaa.in-addr.arpa. 3600 IN    PTR     unknown.ord.scnet.net.

;; MSG SIZE  rcvd: 91

As you see, this value is shown for the PTR record: unknown.ord.scnet.net and I cannot get rid of it.

What is wrong?

  • Try running `dig ccc.bbb.aaa.in-addr.arpa. ns`, and you'll see which servers are actually authoritative for that zone. They're not yours. Generally, they'll belong to your ISP. – Gordon Davisson Aug 16 '20 at 08:10

You don't own the IP address so you can't change the PTR record. Only the IP address owner -- your hosting provider -- can do that. You will need to contact them to find out how to change the record. Most providers have some sort of control panel that provides this functionality.
